New fossil trove documents recovery of life on Earth after dinosaur-killing asteroid impact

Scientists have discovered an extraordinary collection of fossils that reveal in detail how life recovered after a catastrophic event: the asteroid impact that wiped out the dinosaurs 66 million years ago at the end of the Cretaceous Period.

Mammals and their relatives thrived, diversified during so-called ‘Age of Dinosaurs,’ researchers show

Old myths state that, during the time of the dinosaurs, mammals and their relatives were small and primitive. But new research shows that, during the time of the dinosaurs, mammals and their relatives actually underwent two large ecological radiations, diversifying into climbing, gliding and burrowing forms with a variety of diets.

Flowering plants, new teeth and no dinosaurs: New study sheds light on the rise of mammals

Well-preserved fossils ― like this Yanoconodon allini (Specimen No.: NJU P06001; Formation: Yixian; Age: 122.2–124.6 million years ago; Provenance: China) ― enabled the team to infer ecology of these extinct mammal species and look at changes in mammal community structure during the last 165 million years.

A new study published April 30 in the Proceedings of the National Academy of Sciences identified three factors critical in the rise of mammal communities since they first emerged during the Age of Dinosaurs: the rise of flowering plants; the evolution of tribosphenic molars in mammals; and the extinction of non-avian dinosaurs, which reduced competition between mammals and other vertebrates in terrestrial ecosystems.

A new study by paleontologists at the Burke Museum of Natural History & Culture and the University of Washington describes an early marsupial relative called Didelphodon vorax that lived alongside dinosaurs and had, pound-for-pound, the strongest bite force of any mammal ever recorded.

Scientists find oldest dinosaur – or closest relative yet

Artist's drawing of what Nyasasaurus parringtoni looked like

Researchers have discovered what may be the earliest dinosaur, a creature the size of a Labrador retriever, but with a five foot-long tail, that walked the Earth about 10 million years before more familiar dinosaurs.

Dinosaur die out might have been second of two closely timed extinctions

Some mammals used highly complex teeth to compete with dinosaurs

New research shows that at least one group of small mammals, the multituberculates, actually flourished in the last 20 million years of dinosaurs reign and survived their extinction.

Horner to speak on ‘How to Build a Dinosaur’ March 5

Can dinosaurs be brought back to life? Is there a velociraptor lurking in the cells of every chicken? Does extinction have to be forever? Jack Horner, one of the most influential paleontologists of our time, will tackle these questions and more at the 2010 Burke Lecture at 7 p.


Dinosaurs and their closest relatives originated earlier than thought

A team of paleontologists that includes Christian Sidor from the UW has discovered a dinosaur-like animal — one that shared many characteristics with dinosaurs but fell just outside of the dinosaur family tree — living 10 million years earlier than the oldest known dinosaurs.
